SPECIFICATION forming part of Letters Patent No. 706,926, dated August12, 1902. Application filed November 12, 1901. $erial No. 82,033. (Nomodel.)

To all whom it may concern:

Be it known that I, XAVIER PIERRE GIL- ARDONI, engineer, a citizen ofthe Republic of France, and a resident of Ohoisy-le-Roi, in

the Republic of France, have invented a new and useful Improvement in orRelating to Tile-Presses, which is fully set forth in the followingspecification.

The present invention relates to a construc- IO tion of steam-pressesfor the manufacture of tiles which are provided in longitudinal andtransverse directions with grooves and ribs constituting the joints andlapping portions as well as the interior grooves forming the x5 hollowportion of the tiles.

In the accompanying drawings, Figure 1 is a side elevation .of theright-hand side of amachine according to this invention. Fig. 2 is afront elevation of the same. Fig. 3 is a side View of the left-hand sideof the press, and Fig. 4 shows the construction of the two halves of themolds and of the molding device for the internal grooves.

Upon the lateral parts of a solid frame G 2 5 are provided spaces whichserve as guides for the vertical reciprocation of movable slides. Theslides form the supports of a shaft a, Figs. 1 and 3, carrying amulti-angular roller II with five, six, or more sides or faces, each 0of which serves as a support of a semimold 0, Fig. 4, the upper half mof which is fixed upon the top of the press and just opposite to thelower half-mold. Upon the shaft 66 is also rigidly mounted a star-wheelwith six 5 arms E, Fig. 3, with which engages a cam D,

provided at its end with a roller and connected to the operatingmechanism by any suitable transmission mechanism, Figs. 1 and 3. Theshaft 0, which carries the cam, also carries other cams w, engaginglarge frictionrollers M, arranged parallel to the slides abovementioned, these cams in their rotation raising andlowering thefriction-rollers, together with the slides and the angle-roller 5 II.Arms 8, Figs. 1 and 2, secured to the slides, participate also in thisrising movement, and thereby raise the arms n of a table 7', which inthis manner is moved vertically in guides 41 o of the frame y. The table0' carries the fork or device for forming the The rotary prism 11 isgrooves in the tiles.

stopped in proper position after rotation by cam D by means of abrake-wheelB on shaft a, which wheel is engaged by the brake-band B,connected, as usual, to the pivoted weight 5 5 ed brake-lever B On theside of the frame G are arranged arms ff, Fig. 1, whichslidehorizontally in the guides 71. h, fixed upon the frame, and which areacted upon by a cam (1, which has a circular motion between two stops ortappets it, fixed upon the arms ff. Under the action of the cam 61 andarms ff rocking arms g, pivoted at n, and levers 2', connected to theirupper ends, receive a motion by 65 which they are moved nearer to orfarther away from the frame of the machine, with the object ofintroducing or withdrawing the fork j. The approach of the fork iseffected during the ascent of the lower mold and of the angle-roller orprism which carries it, while the withdrawal of the fork is accomplishedafter the pressing operation and before the lower prism has commencedits descending For this purpose the cams are suitably shaped.

The operation of the machine is as follows: On the face of the prism orangle-roller H in front of the machine t'. e., at the side of thepivoted arms or levers gis placed a block of So clay of aslightly-larger size than the finished product and having as manyperforations as the number of teeth of the fork. These perforations giveto the cake the approximate shape of the finished tile. The cam D then 8causes the star-wheel E to make a sixth of a revolution in the backwarddirection, and consequently the prism turns in the same directionthrough an equal angle corresponding to one-sixth of a revolution. Assoon as this rotation is complete under the action of the cam D thefriction-rollers M, Fig. 2, engage with the cams w, whereupon therollers, slides, and the prismatic carrier, as well as the lower mold,ascend in a vertical direction. At a 5 point of this ascending motionthe horizontal arms 3 come in contact with the vertical arms 7% of thetable r, whereupon the latter also partakes in the ascending motion. Atthe same time the pivoted arms or levers g oscil- 1C0.

with the point e as shown in Fig. 1. In consequence of this movement thelever i has pushed the forkj in the mold in such a mannor that theintroduction of the fork into the grooves of the block is finishedbefore the pressure of the angular roller or prism and its half-moldupon the other half-mold fixed on the top of the press is effected. Thepressure being once effected the pivoted levers are swiftly movedbackward through the operation of the horizontal arms ff and theiroperating-cams in such a manner that the fork is withdrawn from the moldbefore the prism commences its downward movement. This latter operationis then effected, and during the end of the movement the starwheel E,Fig. 4, causes the prism to rotate, which brings a fresh cake upon theupper part. At the same time the pressed tile appears on the oppositeside to that through which the cake was introduced and is re moved bymeans of a suitable carrier, as in ordinary machines.

Fig. 4 shows the prism H in its most elevated position. In this positionthe horizontal part 0, constituting the lower part of the mold, forms,with the upper stationary part 'm and the collarp of theteeth of thefork, a complete closed mold. The teeth of the fork are conicallyfinished off or beveled at their ends to in order to facilitate theirwithdrawal, and the upper and lower parts are provided with thenecessary grooves andprojections for the production of joints and lapsof the'lile. The half-molds may be of cast-iron covered with a plasterof the desired thickness, as is usual for the ordinary molding of tilesin soft clay.

The invention effects an improvement of the greatest importance in themanufacture of tiles, owing to the fact that with one and the samepressure action joining and lapping tiles of all shapes can be obtained,provided at the same time at their lower part with thin walls formingplasters, puggings, or ceilings under roofs, formed by the titlesthemselves under conditions which no other system has yet realized.
